Articulated Concrete Blocks

ACBs provide a hard armor surface that is an alternative to rip rap. A matrix of individual concrete blocks placed together to form an erosion-resistant overlay with specific hydraulic performance characteristics. The flexible, interlocking matrix of concrete blocks of uniform size, shape and weight connected by a series of cables which pass longitudinally through preformed ducts in each block. ACBs are flexibility to mold to an existing area and they provide the necessary erosion protection while providing the ability to allow vegetation to grow throughout the entire system. ACBs helps to prevent erosion of exposed soil services and helps to stabilize the land. Typical applications include channels, shoreline restoration and boat ramps.
